AWS Elastic Beanstalk [错误] 2540#0：*1 连接到上游时 connect() 失败（111：连接被拒绝）

Question

我在尝试使用 AWS Elastic Beanstalk 连接到我的 Django 代码时收到此错误：

[error] 2540#0: *1 connect() failed (111: Connection refused) while connecting to upstream, client: 172.31.23.63, server: , request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8000/", host: "172.31.14.130"

我的日志显示如下：

之前，我也收到一个错误，其中写着

Dec 21 04:14:38 ip-172-31-14-130 web: Invalid HTTP_HOST header: '172.31.14.130'. You may need to add '172.31.14.130' to ALLOWED_HOSTS.
Dec 21 04:14:38 ip-172-31-14-130 web: Bad Request: /

我确实将 172.31.14.130 添加到了 settings.py 文件的 ALLOWED_HOSTS 部分，然后收到了 /var/log/nginx/error.log，当我尝试访问我的网页时，它告诉我该网站响应时间太长 -任何帮助/建议将不胜感激！

你应该使用express来监听8000端口，因为它尝试监听http://127.0.0.1:8000/

const port = process.env.port || 8000;
app.listen(port, ()=>{console.log(`listening on port ${port}....`)})

您还可以在配置 -> 系统 -> 环境属性下的 AWS EB 环境变量中设置端口。下面的例子。
